What is the internal angle of a regular pentagon?
Each internal angle measures 108 degrees
What is the measure of one angle of a regular convex 20-gon?
A triangle has an internal angle of 180/3 A square has an internal angle of 360/4 A pentagon has an internal angle of 540/5 An 'x'-agon has an internal angle (180(x-2))/x = (180x-360)/x = 180 - 360/x A 20-agon has an internal angle of 180 - 360/20 = 162
A regular polygon has an interior angle with a measure of 135how many side does the polygon have?
The number of sides of a regular polygon is 360 divided by the size of the exterior angle. The external angle is 180 - the internal angle. So for a regular polygon with an internal angle of 135 we get the following. 360 / (180 - 135) = 360 / 45 = 8 sides
What is the exterior angle of a octagon?
The external angle of a regular octagon is 225 degrees. Each internal angle of a regular octagon is 135 degrees.

What is the angle of friction of silica sand?
35
What is the angle of internal friction for sandstone?
The basic friction angle for sandstone is 26 degrees to 35 degrees. This angle changes based on how wet the stone is.
Does sand reduce friction?
No, sand does not reduce friction but increase friction.
What is the internal coefficient of friction for fertilizer?
It is the Emptying Angle of Repose that is greater than the Filling Angle of Repose. It is always the greater of the two Angles of Repose.
Is angle of friction equal to angle of repose?
yes, angle of friction is equal to angle of repose.
What is the relation between angle of friction and angle of repose?
Angle of repose is equal to angle of friction.
Why does a heap of sand have a pyramidal shape?
If you drop small particles like sand they roll and form a natural angle. (Just steep enough to be held by friction.) Further particles keep rolling and the angle stays the same. This makes the natural shape.
Is internal friction a thing?
Yes. Internal friction exists.
What is the angle of internal friction for clay?
Till is a term describing an unsorted sediment of varying composition. It consists of several different grain sizes and can contain different amounts of clay. As the angle of internal friction is based on the cohesion and grain size of the material the answer is that it varies depending on the composition of the specific till.
What is the difference between angle of friction and angle of repose?
Angel of repose is different from the angel of friction; however in a particular case it may be the same. Basically angle of repose is an engineering property of granular materials. It is the maximum angle of a stable slope determined by friction, cohesion and the shapes of the particles. When bulk granular materials are poured onto a horizontal surface, a conical pile will form. The internal angle between the surface of the pile and the horizontal surface is known as the angle of repose and is related to the density, surface area and shapes of the particles, and the coefficient of friction of the material. Material with a low angle of repose forms flatter piles than material with a high angle of repose. In other words, the angle of repose is the angle a pile forms with the ground. While angel of friction is the angle between the noemal force and athe resultant between tha normal force and friction force.
What is angle of friction?
The angle of friction is defined as the angle of a plane where a body placed on the plane will start to slide.
Internal friction angle of granitic rock?
I usually adopt a frictional angle of 40° to 42°. I've seen some books suggesting 47° to 51° depending on the type of granite.
